Manchester Code

Postby tanlipseong » Tue May 04, 2010 9:21 am

Hi Ben,

I need to develop application using ISM Band FSK RF transmitter and receiver, understand that the data need to be Manchester Coded for reliable Tx and Rx.

Is there any easy way flowcode3 can do the coding and decoding?

Hello,

This RC5 example uses Manchester encoding. You may be able to aquire a bit of information on how this is done from the example provided.

Benj,

The code looks very complicated, not easy for me.

I plan to use FSK ISM band TX RX module for the purpose of sending data, if do not use manchester code, will it be successful and reliable?

if you tried before please comment a little bit details/more

Hello,

A quick look at the device datasheet seems to indicate that you can simply send data down the RF connection using the module. To do this you could simply connect up the tx pin of the UART on one end with the transmitter module and connect up the rx pin on the other end with the receiver module. This should work reliably to give you 9600 baud or lower.
